Analysis of deflection of reinforced concrete elements after demoulding

Abstract eng:
The content of this article is strut-and-tie modelling including the behaviour of early age concrete and analysis of deflections of reinforced concrete elements after demoulding. Good knowledge of the behaviour of concrete at early age plays an important role in setting the deadline for removal of formwork and props. Material parameters and time-dependent deformation such as creep and shrinkage were in this work determined based on measurements and by using the microstructure development function. The results are deflections depending on the time of demoulding and the influence of support by props. The results are compared with the limit values. The proposed analysis of the instant of demoulding may be of practical use and can lead to proper intervals or technological breaks and can reduce the amount of formwork required for construction.
